    Which capacitor to buy as a replacement

    I need to replace a 1200uf 25v Sam Young NXE capacitor for my Samsung TV. I know that I can get a capacitor with a higher voltage, but I feel like I should just try to find a replacement with as close to the original specs as possible. I’m looking to get a better manufacturer like Panasonic.

    My question is, how important is it to match the ESR, impedance, and ripple current? Because I don’t know these values for the original one. I found this chart which might help. https://cdn.badcaps-static.com/pdfs/...3307201ded.pdf

    I was looking to buy one of these but I just don’t know which to choose as they have different values besides the capacitance and voltage. (Like impedance and ripple current) https://www.digikey.com/products/en/...5v%20capacitor

    They would be fine. Match the leg spacing, width of capacitor and also its height if in a confined space.

      I would replace other caps as well too.

        So the impedance and ripple current don't really matter? The old Sam Young capacitor seems to be advertised as ultra low ESR which is why I ask.

          Ripple current does matter however the Panasonic range of electrolytic capacitors are a good choice. No doubt there are other makes but they tend to be my preference.
